Why We Need You 🚀


We’re building the next generation of Perifit products — smarter, smaller, and even more empowering. We’re looking for a Senior Electronic Engineer to lead the electrical design of our low-power, connected, and sensor-rich devices.

You’ll play a central role in designing, validating, and industrializing electronic systems for both existing products and brand new developments. You’ll work closely with our firmware, mechanical, and industrialization teams — and take full ownership of the electronics domain, from early prototypes to mass production.

What You Will Be Doing

* Lead the electronics design of new and existing Perifit products — including our next-generation wearable breast pump and pelvic trainers.
* Own schematics, layout, and BOM optimization for low-power, battery-operated, Bluetooth-connected devices.
* Design and validate circuits for signal acquisition, BLE communication, motor control, and sensor interfaces — focusing on ultra-low current and low-voltage performance.
* Build and test functional prototypes to evaluate signal integrity, noise, and power consumption.
* Perform initial firmware work (bare-metal or with SDKs) to validate hardware performance and integration.
* Collaborate with mechanical and firmware engineers to ensure optimal component placement, enclosure integration, and system-level reliability.
* Manage relationships with PCBA suppliers and EMS partners — including DFM review, factory communication, and occasional travel to China.
* Support Customer Service and Quality teams by investigating technical issues reported by users, identifying root causes, and contributing to product improvements.
* Support EMC/CE/FCC pre-compliance and certification testing.


What Hard Skills We Need to See 🛠️


* Electronics Design Expertise: Strong skills in schematic capture and PCB layout using tools like Altium, KiCad, or similar. Proven experience in low-power system design and wireless devices.
* Power and Signal Proficiency: Solid knowledge of battery-powered electronics, motor drivers, signal conditioning, and ultra-low-current digital circuits.
* BLE and Wireless: Familiarity with BLE modules, RF layout basics, antenna integration, and debugging wireless performance.
* Prototyping & Debugging: Experience bringing up new boards, running basic firmware tests, debugging hardware issues with scopes, analyzers, and test jigs.
* Manufacturing and DFM: Comfortable working with overseas PCBA suppliers to ensure production-quality builds and scalable, testable designs.
* Documentation & Certification: Ability to create thorough documentation and contribute to product compliance efforts (EMC/CE/FCC).


What Kind of Person We Are Looking For 👤


* Builder & Debugger: You love turning circuits into reality, figuring out why something isn’t working, and improving it until it shines.
* Cross-functional Collaborator: You communicate clearly with mechanical, firmware, and product teams — and enjoy working together to solve system-level challenges.
* Autonomous and Structured: You’re organized, proactive, and able to take full ownership of your scope without constant oversight.
* You are a feminist: You believe every woman deserves access to innovative health solutions. You’re comfortable working on intimate health topics and excited to contribute to positive change.


You Will Shine If ✨


* You’ve brought at least one full product to mass production, handling layout, design review, supplier interface, and electrical testing.
* You’ve worked on wearable, IoT, or battery-powered consumer products with tight constraints on size, power, and performance.
* You’ve implemented or tuned BLE antennas, motor drivers, or ultra-low-power sleep modes.
* You enjoy taking a hands-on approach to validation, measurement, and iteration, with an eye for reliability and elegance.
